In receive path, an adaptive each channel, and different types of loopbacks can be set on a per channel equalizer is integrated to remove the distortion introduced by the cable basis. Four different kinds of line terminating impedance, 75 , 100 110 attenuation. The IDT82P5088 also performs clock/data recovery, AMI/ and 120 are selectable on a per channel basis. The chip also provides B8ZS/HDB3 line decoding and detects and reports the LOS conditions. In driver short-circuit protection and supports JTAG boundary scanning. the transmit path, there is an AMI/B8ZS/HDB3 encoder, waveform shaper, The IDT82P5088 can be used in SDH/SONET, WAN, routers, wireless LBOs and jitter attenuator for each channel. The jitter attenuators in both base stations, IADs, IMA, IMAPs, gateways, frame relay access devices, the transmit path and receive path can be disabled. The IDT82P5088 sup- CSU/DSU equipment, etc. ports both single rail and dual rail system interfaces.
